Method of forming a container packaging with ambient fill and diaphragm inversion

Abstract

Disclosed is a method of forming a packaging, the method including the steps of: providing an empty container including a sidewall, an opneck and a base, the container further including a invertible diaphragm in an outwardly-protruding position; a filling step of pouring, within the container through the neck, a product at a temperature lower than or equal to ambient temperature; a capping step of sealingly closing the filled container by way of a cap mounted onto the neck; an inversion step of displacing the diaphragm to an inwardly-protruding position, the inversion step being conducted within seconds after sealingly closing the container.

1 . Method of forming a packaging, said method including the steps of:
 providing an empty container ( 1 ) comprising a sidewall ( 5 ), an open neck ( 2 ) and a base ( 7 );   a filling step of pouring, within the container ( 1 ) through the neck ( 2 ), a product ( 16 ) at a temperature lower than or equal to ambient temperature;   a capping step of sealingly closing the filled container ( 1 ) by means of a cap ( 18 ) mounted onto the neck ( 2 );   
       wherein:
 the container ( 1 ) includes an invertible diaphragm ( 9 ), said diaphragm ( 9 ) being in an outwardly-protruding position; 
 the method further includes an inversion step of displacing the diaphragm ( 9 ) to an inwardly-protruding position, said inversion step being conducted after sealingly closing the container ( 1 ), the inversion step being initiated before completion of the capping step. 
 
     
     
         2 . Method according to  claim 1 , wherein the base ( 7 ) of the container ( 1 ) includes a high standing ring ( 8 ) and the invertible diaphragm ( 9 ) is centrally provided on the base ( 7 ). 
     
     
         3 . Method according to  claim 1 , wherein the temperature of the poured product is lower than or equal to 40° C. 
     
     
         4 . Method according to  claim 3 , wherein the temperature of the poured product ( 16 ) is lower than or equal to 20° C. 
     
     
         5 . Method according to  claim 1 , wherein the product ( 16 ) is water. 
     
     
         6 . Method according to  claim 1 , wherein the inversion step is conducted by means of a mechanical pusher ( 22 ). 
     
     
         7 . Method according to  claim 2 , wherein the temperature of the poured product is lower than or equal to 40° C. 
     
     
         8 . Method according to  claim 2 , wherein the product ( 16 ) is water. 
     
     
         9 . Method according to  claim 3 , wherein the product ( 16 ) is water. 
     
     
         10 . Method according to  claim 4 , wherein the product ( 16 ) is water. 
     
     
         11 . Method according to  claim 5 , wherein the product ( 16 ) is water. 
     
     
         12 . Method according to  claim 2 , wherein the inversion step is conducted by means of a mechanical pusher ( 22 ). 
     
     
         13 . Method according to  claim 3 , wherein the inversion step is conducted by means of a mechanical pusher ( 22 ). 
     
     
         14 . Method according to  claim 4 , wherein the inversion step is conducted by means of a mechanical pusher ( 22 ). 
     
     
         15 . Method according to  claim 5 , wherein the inversion step is conducted by means of a mechanical pusher ( 22 ). 
     
     
         16 . Method according to  claim 7 , wherein the inversion step is conducted by means of a mechanical pusher ( 22 ). 
     
     
         17 . Method according to  claim 8 , wherein the inversion step is conducted by means of a mechanical pusher ( 22 ). 
     
     
         18 . Method according to  claim 9 , wherein the inversion step is conducted by means of a mechanical pusher ( 22 ). 
     
     
         19 . Method according to  claim 10 , wherein the inversion step is conducted by means of a mechanical pusher ( 22 ). 
     
     
         20 . Method according to  claim 11 , wherein the inversion step is conducted by means of a mechanical pusher ( 22 ).
